Wouldn’t it be amazing if you could pause the program execution and print the value of all the variables? Well, it turned out someone had already thought of this. If, for example, you forget to print the result of a variable, you would need to re-write, re-compile and re-run the program. Writing that bunch of logs was helpful to understand the current state of the program execution and to find bugs. $ Now I'm in the iteration 3 of the while loop The output of my console would now be something like: I added some logs to my code to understand what was happening (AKA Writeln() everywhere). I was writing my first bugs.Īt that moment I barely knew what the word ‘debug’ even meant, so I did what all programmers do. The output of the console started coming up incorrect. Soon, questions began rattling around my head (and not just about why the tutor made us use a programming language which was used to code the Apple II 40 years ago).Īs the algorithms became more complex, and started calculating things like the greatest common divisor, I began getting unexpected outcomes. A simple program for adding two numbers. Once written, we pressed the execute key and waited for the result. In my first-ever computer programming tutorial (called, very imaginatively, Initiation to Programming), we wrote an algorithm in Pascal to perform a series of simple operations, like printing the sum of two numbers to the console. To answer this question, let’s take a little trip down memory lane. Reading time: 10 minutes Ok first of all, what’s a breakpoint on iOS and Android ecosystem? To kick off our series on debugging for software developers, we tell you how to build breakpoints step by step using Xcode and breakpoint Android Studio to isolate key information about your app’s performance, and save crucial time during the process.
